For some reasons not yet fully understood your machine B does no cluster
forward. There should be a log line like "check_ldap: forwarding session
to A". Check ~control/ldapcluster and the mailHost attribute.
Currently it tries a local pop3 session and fails horribly.
Could you post some more info? Mainly ~control/ldapclu* and a sample ldif?

This has nothing todo with qmqpd as the pop3 session forwarding is done
internaly.
